Ball Lock Ejector Punches Light Duty XNM Coated X-Shaped Tip

Ball lock ejector punches are used in injection and die assemblies where a “ball lock” mechanism must engage reliably to transmit force for ejection. This light-duty variant is suited for metric tooling that prioritizes stable actuation and repeatable stripping under lower load cycles.

• Automotive connector and small housing molds: The point geometry being larger than the shank helps maintain consistent ball lock engagement, improving ejection uniformity for delicate parts.
• Appliance and consumer electronics enclosures: Use cases with controlled, light-load ejection benefit from the wear-resistant XNM coating that helps preserve performance during repeated cycles.
• General die assemblies requiring precision ball-lock behavior: The configurable tip shapes (H, J, K, L, N, O, R, V, X, Y, Z) allow matching contact geometry to specific punch-point requirements for stable motion.

Overall, the X-shaped tip options and XNM coating support reliable actuation where toughness demands are moderate and dimensional repeatability is important.

The provided datasheet specifies an XNM coating for this ejector punch, intended to improve wear resistance and maintain forming/ejection performance during light-duty cycles. While the underlying steel grade and exact heat treatment (e.g., quenched & tempered, nitrided) are not stated in the input, the coating choice indicates a surface-focused durability strategy rather than bulk hardness optimization.

• Wear resistance: The XNM coating helps resist point and locking-area wear, supporting consistent ball lock engagement.
• Toughness vs. hardness trade-off: For light-duty applications, the design focus is stable ejection repeatability; extremely high bulk hardness is typically less critical than maintaining surface integrity at the tip.
• Heat treatment state: Not specified in the input data; confirm the base material and heat-treatment condition from the manufacturer for exact HRC and dimensional stability expectations.

If you need higher impact resistance or longer life under heavier cycles, compare with variants offering different coating systems or documented bulk hardening/tempering specifications.

Select dimensions by matching the shank and point profile to the ball-lock pocket and ejector interface in your metric mold tooling. The punch provides D (shank diameter) options of 13, 16, 20, 25, 32 mm, so choose the D value that matches the bore/guide and locking features for proper alignment.

• Length setup: Use L = 80 ～ 100 mm to achieve the required stroke clearance and ensure full actuation without bottoming in the guide system.
• Point length: Set L1 = 19 ～ 30 mm according to the required reach into the part/mating cavity surface and ball-lock engagement region.
• Point design matching: Confirm the Tip Shape (H, J, K, L, N, O, R, V, X, Y, Z; this variant notes an X-shaped tip option) to match your contact shape requirements.

Use the specified P and W ranges (e.g., P: 13.1 ～ 32, 16.1 ～ 38, 20.1 ～ 40, 25.1 ～ 44, 32.1 ～ 50 mm; W: 1.57 ～ 27.8 mm) and R (0.2 ～ 16 up to 0.2 ～ 25 mm) to ensure the locking/transition geometry clears neighboring features. Tolerance details are not included in the input, so verify fit tolerances with your supplier drawings or standard punch fits for the corresponding D size.
